How do I use VirtualDub2 to remultiplex a video (addition: with a different frame rate) from MKV to MP4?

I think it would also be most useful if VirtualDub2 could be configured to save a selected quantity of frames (between key or I-frames) into the same container as the source or as an elementary stream.

VirtualDub2 doesn't (for me) update the Audio Display when playing. It's fine when stepping with cursor keys, page up/down, or scrubbing on the timeline with the mouse, but hitting space to play just causes the currenty displayed waveforms to scroll off to the left with no new waveform data replacing it from the right. The frame numbers update, though.

Are you playing avisynth script? Currently the waveform can update during playback only when using caching input driver.
This is because audio must be read concurrently on two threads, and most sources do not support this. I was thinking on possible solution, best I can imagine is to buffer a window long enough to satisfy both ends. This feels surprisingly complex.

These are actually HKEY_CURRENT_USER
You can run once virtualdub.exe /portable and it will create VirtualDub.ini, or you can just create a blank file yourself.
All VirtualDub settings will go to ini file instead of registry.
But plugins will continue to use registry (e.g. Script Editor)

I have tried again with VirtualDub2_43364 (no added external plugin), empty VirtualDub.ini and then double click on "VirtualDub64.exe" (I'm using win8.1pro 64bit on non admin account):
